摘要
针对三峡地区500kV架空输电线路多次发生融冰闪络故障的现象,从线路所经过地区的环境和运行特点着手,分析了线路融冰闪络的原因及形成特点,提出了具体的防线路融冰闪络措施并设计了一种防融冰闪络装置。
Aimed at the frequent flashover of 500 kV transmission line in three gorges area due to ice-melting,the causes of the flashover were analyzed in respect to the features of environment along the line and its operation.The countermeasure was put forward and the device for the prevention of flashover due to ice-melting was developed.
